Description

Technical Field

[0001] This utility model relates to the field of steel cage technology, specifically to a platform for manufacturing unconventional large-diameter steel cages. Background Technology

[0002] A fabrication platform for unconventional large-diameter steel cages is a specialized production equipment designed specifically for steel cages with unconventional diameters. Its core function is to achieve stable support, precise positioning, and efficient fabrication of large-diameter steel cages, solving the technical pain point that traditional equipment cannot adapt to large diameters.

[0003] In existing technologies, traditional installation requires the use of a welding machine or manual labor to install the stirrups of the rebar cage. This method is only suitable for small-diameter stirrups; large-diameter rebars cannot be bent, and the welding machine requires a high economic investment. Welding machines are large pieces of equipment, demanding high standards for foundation treatment and skilled operators. Manual installation is only suitable for small-diameter, lightweight rebar cages, making it difficult to guarantee construction accuracy. If the device can only accommodate a single diameter, multiple platforms need to be customized for rebar cages of various sizes, increasing equipment costs and leading to potential post-project idleness and waste. It also hinders rapid production switching, requiring modifications for even slight diameter changes, severely slowing down construction efficiency and delaying the project schedule. Forced adaptation can result in unstable rebar cage fixation, causing displacement and tipping, posing safety hazards and affecting welding quality. Furthermore, it makes it difficult to address design changes or temporary needs, further hindering project progress. Utility Model Content

[0004] The purpose of this utility model is to provide a fabrication platform for unconventional large-diameter steel cages, in order to solve the problem mentioned in the background art that the use of a rolling welding machine or manual installation of steel cage stirrups results in the inability to bend large-diameter steel bars and difficulty in ensuring construction accuracy.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a fabrication platform for unconventional large-diameter steel cages, including a support connecting seat, a support base fixedly connected to the support connecting seat, an adjustment component installed on the support connecting seat, a first jack, a second jack, a third jack, a third jack, and a fourth jack installed on the adjustment component, a support beam fixedly connected to the first jack, the second jack, the third jack, and the fourth jack, main reinforcing bars installed on the support beam, and main reinforcing bars installed inside the inner stirrups, wherein the first jack pushes the support beam to move in a preset reverse direction.

[0006] Based on the preferred embodiment of this technical solution, the supporting beam is arc-shaped, and the arc surface of the main reinforcement connection fits onto the arc surface of the supporting beam.

[0007] In the preferred embodiment of this technical solution, there are two first jacks, and the two first jacks are symmetrically installed on the adjustment assembly.

[0008] In a preferred embodiment of this technical solution, the adjustment assembly includes a rotating connecting rod rotatably connected inside the support base, a first bevel gear fixedly connected to the rotating connecting rod, a rotating adjusting rod fixedly connected to the rotating connecting rod, a bidirectional threaded rod rotatably connected inside the support base, a second bevel gear fixedly connected to the bidirectional threaded rod, a sliding threaded seat threadedly connected to the bidirectional threaded rod, and a fixed limiting rod fixedly connected inside the support base. The sliding threaded seat is slidably connected to the fixed limiting rod, the first bevel gear is meshed with the second bevel gear, and the rotating adjusting rod is manually driven to rotate the rotating connecting rod clockwise or counterclockwise.

[0009] Based on the preferred embodiment of this technical solution, two fixed limiting rods are provided, and the two fixed limiting rods are symmetrically fixedly connected to the support base.

[0010] In the preferred embodiment of this technical solution, two sliding thread seats are provided, and the two sliding thread seats are symmetrically threadedly connected to the bidirectional threaded rod.

[0011] In the preferred embodiment of this technical solution, the support base has a groove at the corresponding position of the sliding threaded seat, and the sliding threaded seat is slidably connected inside the support base.

[0012] Compared with the prior art, the beneficial effects of this utility model are: 1. By combining multiple sets of jacks and supporting beams, the height and position can be flexibly adjusted, adapting to unconventional large-diameter rebar cages of varying diameters. Unlike welding machines, which are limited by diameter, this design avoids the limitation of manual labor only being able to handle small diameters. Secondly, it significantly reduces costs and site requirements. There's no need to invest in high-cost large welding machines or perform expensive foundation treatments, resulting in significantly reduced equipment investment and site modification costs. Finally, it offers superior precision and safety. The jacks ensure stable support of the supporting beams for the main reinforcement and inner stirrups, preventing displacement caused by uneven load distribution during manual installation and guaranteeing forming accuracy. Furthermore, it eliminates the need for highly skilled operators, lowering the barrier to entry for manual labor. It also overcomes the limitations of manual installation of small-diameter, lightweight rebar cages, making it suitable for the fabrication of large-diameter, heavy-duty rebar cages.

[0013] 2. By manually driving the adjusting rod, the bidirectional threaded rod can be rotated through the meshing transmission of the first and second bevel gears. This eliminates the need for complex power equipment, making operation easy for ordinary construction workers and avoiding the high requirements for professional operators found in traditional equipment. Furthermore, it offers wide applicability and precise adjustment. The bidirectional threaded rod drives two symmetrical sliding threaded seats to move synchronously in opposite directions, allowing for quick adjustment of the distance between the jack and the support beam. This easily adapts to unconventional large-diameter rebar cages of varying diameters, eliminating the need for customized equipment to accommodate diameter changes, unlike traditional platforms, thus reducing equipment investment and resource waste. Finally, it provides stable adjustment and high durability. The dual limiting mechanism of the fixed limit rod and the support base groove ensures smooth and stable movement of the sliding threaded seats, improving adjustment accuracy and guaranteeing the quality of the rebar cage forming. Simultaneously, the dual limit rod structure disperses friction, reducing component wear, extending component lifespan, and lowering subsequent maintenance costs. Attached Figure Description

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] Please see Figure 1-5This utility model provides an embodiment of a fabrication platform for unconventional large-diameter steel cages: it includes a support connecting seat 1, a support base 2 fixedly connected to the support connecting seat 1, an adjustment component installed on the support connecting seat 1, a first jack 701, a second jack 702, a third jack 703, a third jack 704 and a fourth jack 704 installed on the adjustment component, a support beam 705 fixedly connected to the first jack 701, the second jack 702, the third jack 703 and the fourth jack 704, main reinforcement bars 4 installed on the support beam 705 and main reinforcement bars 4 installed inside the inner stirrups 3, and the first jack 701 pushes the support beam 705 to move in a preset reverse direction. By combining the first jack 701, the second jack 702, the third jack 703, the fourth jack 704, and the supporting beam 705, the height and position of the supporting beam 705 can be flexibly adjusted, enabling the platform to adapt to unconventional large-diameter steel cages of different diameters, thus overcoming the limitation of traditional platforms that can only fix a single diameter. At the same time, the pushing force of each jack can ensure that the supporting beam 705 provides stable support for the main reinforcement 4 and the inner stirrups 3, avoiding displacement or tilting caused by uneven load during the manufacturing process, thereby improving construction safety and the forming accuracy of the steel cage.

[0018] Please see Figure 2-3 A further solution based on this embodiment is as follows: the supporting beam 705 is arc-shaped, and the arc surface of the main reinforcement 4 is attached to the arc surface of the supporting beam 705. By designing the supporting beam 705 as an anti-roll arc shape and attaching it to the arc shape of the main reinforcement 4, the contact area between the two can be increased, making the supporting force on the main reinforcement 4 more uniform and reducing the deformation of the main reinforcement 4 caused by local stress concentration.

[0019] Please see Figure 2-3 A further solution based on this embodiment is as follows: two first jacks 701 are provided, and the two first jacks 701 are symmetrically installed on the adjustment assembly. By symmetrically installing the two first jacks 701, the force on both sides of the support beam 705 can be balanced when it is under force, avoiding tilting or deformation of the support beam 705 due to excessive force on one side.

[0020] Please see Figure 4-5A further embodiment of this solution is as follows: the adjustment assembly includes a rotating connecting rod 801 rotatably connected inside the support base 2, a first bevel gear 802 fixedly connected to the rotating connecting rod 801, a rotating adjusting rod 803 fixedly connected to the rotating connecting rod 801, a bidirectional threaded rod 804 rotatably connected inside the support base 2, a second bevel gear 805 fixedly connected to the bidirectional threaded rod 804, a sliding threaded seat 806 threadedly connected to the bidirectional threaded rod 804, and a fixed limiting rod 807 fixedly connected inside the support base 2. The sliding threaded seat 806 is slidably connected to the fixed limiting rod 807, the first bevel gear 802 is meshed with the second bevel gear 805, and the rotating adjusting rod 803 is manually driven to rotate the rotating connecting rod 801 in a clockwise or counterclockwise direction. By manually driving the rotating adjusting rod 803 to drive the rotating connecting rod 801 and the first bevel gear 802 to rotate, and cooperating with the meshing transmission of the second bevel gear 805, the bidirectional threaded rod 804 can be driven to rotate, thereby realizing the synchronous reverse or same-direction movement of the sliding threaded seat 806, adjusting the position of the jack and the supporting beam 705, so that the platform can quickly adapt to the manufacturing needs of steel cages of different diameters.

[0021] Please see Figure 4-5 A further solution based on this embodiment is as follows: two fixed limiting rods 807 are provided, and the two fixed limiting rods 807 are symmetrically fixedly connected to the support base 2. By setting two symmetrical fixed limiting rods 807, stable support and guidance can be formed for the sliding threaded seat 806 from both sides, preventing the sliding threaded seat 806 from deflecting or jamming under the drive of the bidirectional threaded rod 804, and ensuring that it moves smoothly along the preset trajectory; at the same time, the structure of the double limiting rods can disperse the frictional force generated when the sliding threaded seat 806 moves, reduce component wear, extend the service life of the adjustment component, and ensure the long-term stable operation of the platform.

[0022] Please see Figure 4-5 A further solution based on this embodiment is as follows: two sliding threaded seats 806 are provided, and the two sliding threaded seats 806 are symmetrically threaded onto the bidirectional threaded rod 804. By symmetrically threading the two sliding threaded seats 806 onto the bidirectional threaded rod 804, synchronous reverse movement of the two can be achieved when the bidirectional threaded rod 804 rotates, quickly adjusting the distance between the jacks on both sides and the supporting beam 705, and accurately adapting to the support requirements of steel cages of different diameters.

[0023] Please see Figure 4-5A further solution based on this embodiment is as follows: the support base 2 has a groove at the corresponding position of the sliding threaded seat 806, and the sliding threaded seat 806 is slidably connected inside the support base 2. By opening a groove at the corresponding position of the support base 2 and embedding the sliding threaded seat 806 therein, the movement direction of the sliding threaded seat 806 can be further restricted, preventing it from jumping up and down or shifting laterally during adjustment, thus improving adjustment stability.

[0024] Working principle: Manually rotating the adjusting rod 803 drives the rotating connecting rod 801 and the first bevel gear 802 to rotate, which in turn meshes with the second bevel gear 805, driving the bidirectional threaded rod 804 to rotate. Since the two sliding threaded seats 806 are symmetrically threaded onto the bidirectional threaded rod 804, and are guided and limited by the fixed limiting rod 807 and the sliding groove of the support base 2, they will move synchronously in opposite directions. This adjusts the spacing of the first to fourth jacks 704 and the support beam 705 installed on the threaded seats, precisely adapting to the support requirements of steel cages of different diameters. Furthermore, stable operation is achieved through multiple sets of jacks and an arc-shaped support structure. The anti-roll arc design of the support beam 705 fits snugly against the arc of the main reinforcement 4, increasing the contact area and forming a lateral limit. Combined with the balanced force structure of the symmetrically installed double jacks, this ensures that the main reinforcement 4 and the inner stirrups 3 remain stable and do not shift during manufacturing. During operation, by controlling the alternating lifting and lowering of each jack group, space is made for the installation of stirrups, achieving precise segmented allocation, and finally the steel cage is lowered onto the jig to complete the welding.

[0025] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
